Google has acknowledged delays in processing developer token access applications for the Google Ads API due to high demand following the release of Explorer Access, the Google Ads API MCP server, and the Developer Assistant.
The company has added reviewers and fast-tracked some applications, so some developers may already see progress. Google advises developers to stick with Explorer Access unless Basic Access is essential for growth or feature needs.

To support faster approvals, applicants should:
- Ensure accounts are listed under the correct Manager account
- Complete advertiser verification where possible
- Add the Google Cloud project number if OAuth verification was done
- Clearly explain their use case in the application
These steps can help streamline the approval process for developers requesting higher-level API access.
